After NSX deployment we can simply create firewall rules
Here define Group first with AD, DNS, NTP etc services.
Select VM from the list or define IP address of that VM/Service.
Here we will be going to create our Prod, Dev or Test environment groups
You can create custom name also type and then enter
Now we have to define which group can talk to defined group like Infra, DHCP, NTP or custom etc.
